The Ornithoscelida Theory is more accurate and up to date than the Saurischia/Ornithischia theory. Therefore, the taxonomy section should reflect that. Also, the history section should include detail about the transition.68.48.8.60 (talk)12:26, 10 May 2025 (UTC)[reply]

This is not true, Ornithoscelida is far from universally accepted.The Morrison Man (talk)21:58, 10 May 2025 (UTC)[reply]

It seems it's even almost forgotten again?FunkMonk (talk)14:04, 11 May 2025 (UTC)[reply]

Whether or not this is very accurate, this theory should be explained in the history section of the article.68.48.8.60 (talk)14:18, 11 May 2025 (UTC)[reply]

The Ornithoscelida hypothesis is still not widely accepted, and considered less parsimonious than the traditional hypothesis even when using the same dataset. SeeNorman et al. (2022),Černý & Simonoff (2023),Fonseca et al. (2024), etc. Even Matthew G. Baron, the lead author of the 2017 paper that first supported the Ornithoscelida hypothesis, is more cautious about that hypothesis in his 2024Chilesaurus paper where he states that more work is needed for it.Baron (2024)Junsik1223 (talk)18:55, 11 May 2025 (UTC)[reply]

I understand that it shouldn't be included in the taxonomy section, but the theory should still be explained because it's a major theory in the history of dinosaur zoology. The same could be said for Phytodinosauria.68.48.8.60 (talk)20:49, 11 May 2025 (UTC)[reply]

The theories shouldn't be addressed as if they are correct, but they should at least be mentioned.68.48.8.60 (talk)12:07, 15 May 2025 (UTC)[reply]

It's already mentioned on the page.The Morrison Man (talk)14:26, 15 May 2025 (UTC)[reply]

Where?68.48.8.60 (talk)16:57, 16 May 2025 (UTC)[reply]

"Research by Matthew G. Baron, David B. Norman, and Paul M. Barrett in 2017 suggested a radical revision of dinosaurian systematics. Phylogenetic analysis by Baron et al. recovered the Ornithischia as being closer to the Theropoda than the Sauropodomorpha, as opposed to the traditional union of theropods with sauropodomorphs. This would cause sauropods and kin to fall outside traditional dinosaurs, so they re-defined Dinosauria as the last common ancestor of Triceratops horridus, Passer domesticus and Diplodocus carnegii, and all of its descendants, to ensure that sauropods and kin remain included as dinosaurs. They also resurrected the clade Ornithoscelida to refer to the group containing Ornithischia and Theropoda."

Third paragraph under the 'definition' header.The Morrison Man (talk)17:36, 16 May 2025 (UTC)[reply]

What about the Phytodinosauria theory?68.48.8.60 (talk)00:26, 17 May 2025 (UTC)[reply]

That was never seriously considered by anyone but Robert Bakker.FunkMonk (talk)19:37, 17 May 2025 (UTC)[reply]

It's still very popular and it's a major theory in the history of dinosaur zoology.68.48.8.60 (talk)17:33, 18 May 2025 (UTC)[reply]

Where?FunkMonk (talk)18:31, 18 May 2025 (UTC)[reply]

I noticed a misstructured sentence in the communication section. It goes as follows: He states that they mostly on visual displays and possibly non-vocal sounds, such as hissing, jaw-grinding or -clapping, splashing, and wing-beating (possible in winged maniraptoran dinosaurs).Runawayturtle (talk)00:14, 29 May 2025 (UTC)[reply]

Please edit indentions of dino names so that when people print, it doesn't move to the side. Not easily readable for people with accessibility problems.208.119.81.194 (talk)19:47, 5 June 2025 (UTC)[reply]

You mean the list in the "Taxonomy" section, I assume? I agree that the list is too large and unwieldy for this overview article here. We certainly could simplify that a bit; for a start, all taxa could be removed that don't have their own Wikipedia article (Ceratopsoidea and more), and we could also remove clades below family level. To make the indentions smaller, we would have to abandon the bullet points. Let's see what others think. --Jens Lallensack (talk)20:33, 5 June 2025 (UTC)[reply]

Why do all images in the infobox depict extinct species, whereas those of the bird species are displayed separately? I randomly openedElephantidae andCetacean to note that the their infoboxes combine images of both living and extinct species. --Kiril Simeonovski (talk)11:52, 11 December 2025 (UTC)[reply]

Dinosaurs were a group of animals and they ruled they earth for more than 500 million years.Some dinosaurs likeTyrannosaurus where predators but instead of being loud they where silent this is what many people think today but your thoughts are wrong then. Now too many people think that the dinosaurs are bloody monsters and roar every time they spot you before eating you.This is howJurassic Park view is. But if you think all of this away these scary, roaring dinosaurs are just animals. Who take care of their kids and learn them how to survive. It isn't really easy to get information but it is possible. If you wanna visit a t-rex you should go to Natutralis in the Netherlands to see Trix or to musea in America for Stan and Seu.~2026-10649-71 (talk)10:13, 17 February 2026 (UTC)[reply]
